/*
 * Cut Cares marketing site.
 *
 * No build step, no framework, no external font, no JavaScript. That is a
 * deliberate choice, not laziness: the audience includes people on old phones and
 * slow connections, and it lets the CSP stay at script-src 'none' with no
 * third-party origins — which in turn means the site sets no cookies and needs no
 * consent banner.
 *
 * Accessibility here is a requirement, not a polish pass. Body text is 1.125rem
 * because the readership is disabled and older people; contrast is checked to
 * WCAG AA; every interactive target is at least 48px; all motion is opt-in.
